A group of Don Cossacks took part in the Bulavin Rebellion in opposition to reforms of Peter the Great.
After their defeat, starting from 1737, they began to take refuge in the Ottoman Empire and moved from the Kuban region where some of them, known as Nekrasov Cossacks, had settled earlier.
In a separate event after the dissolution of the Zaporozhian Host and the destruction of the Zaporozhian Sich, up to 5000 Cossacks fled to the Turkish-controlled Danube delta where the Sultan allowed them to form the Danubian Sich.
Some returned to Russia, whilst others were moved to central Turkey and worked in forced labour.
As of 1927, there were three Cossack villages in Turkey: Eski Kazaklar (later officially renamed as Kocagöl, the earlier settlement on the southwestern tip of Lake Manyas) and Yeni Kazaklar (founded by a community that left Eski Kazaklar and located on the northern shore of Lake Manyas) in Manyas district of Balıkesir Province, and Kazak (on the eastern shore of Lake Akşehir) in Akşehir district of Konya Province.
